Hello @david_terentschenko42N9J,
I hope this message finds you well. Could you elaborate on the need, are you asking for a ULP that can open datasheets from specific components in the design? Some users have created ULPs that can do this.
Now if you want something that will document your design there's no ULP that will create a datasheet from your design.
Let me know if there's anything else I can do for you.
Best Regards,
